(54) COMMUNICATION DEVICE AND COMMUNICATION METHOD


(57) in an AP (100), a Trigger frame generator (104) generates a trigger signal instructing an uplink signal transmission, the trigger signal including a terminal information field that includes a terminal ID subfield and a resource unit allocation information subfield, and a radio transmitter/receiver (106) transmits the trigger signal. In a case where the trigger signal includes a first terminal information field specifying one or more contiguous resource units for random access, the Trigger frame generator (104) sets an unused ID that is not to be used as a terminal ID in the first terminal information field.
